Hi everyone this is my first post. I have an i Mac with the Tiger upgrades. I've used Mac for close to 20 years. Now retired and enjoying my computer. The idea behind this Forum sounds ideal and I look forward to participation. Thank you in advance for any help you can give me.
QUESTION
I am receiving an increasing number of pps attachments. I presume these are from Power Point presentations. I operate with OS 3.6 and for some reason I am unable to open these attachments. Has anyone else run into this problem?
If so please share your solution.
